Credit Karma for Android is completely free, and all of the services it offers are free as well. You can check your credit score as often as you like (Credit Karma pulls its data from TransUnion, one of the three big credit reporting companies) and monitor your overall credit rating at any time. You can see your credit "report card," which gives you a broad overview of your credit history and its health, and then drill down if you want more information on anything specific.

The app comes with free credit monitoring, and shows you any alerts on your account, like hard credit inquiries (the kind that can at times damage your credit rating) or if any new accounts have been opened in your name. You'll also get push notifications any time something changes in your credit report, just so you can stay on top of it and act immediately if you're worried someone has stolen your identity. For security, the app can be PIN locked. You can grab it at the link below.
